Multi Step Form Frontend Mentor Solution (HTML, CSS, JavaScript)

What are you most proud of, and what would you do differently next time?

Form validation is something I really wanted to work on, But finding a right project has been tedicious task. After searching many projects I saw this project from the frontend mentor. This is first time I am doing form validation after learning javascript properly. And I am pretty much satisfied with the results obtained. Give it a glance and mention the things how well this was implemented and where it lacks?

What challenges did you encounter, and how did you overcome them?

The major problem I encountered in the project was using the regular expressions for pattern matching the input fields. Now I am familiar with the regular expressions.

What specific areas of your project would you like help with?

The only problem with which I am concerned is the regular expression for the international phone number. If anyone knows how to do this validation just let me know?

Take a moment and look into the projects, will be looking for some suggestions and improvements?
